Guild Wars 2

as a beginner in wvw playing necro with a tanky condition build can anyone give me some advice as to what ability points would be best suited to me?

Get the guard stacks first

get supply mastery 4

How many points do you have to work with? Generally you want to put 4 ranks into supply mastery to have the chance to get supply back when building. 1 rank into build and 1 rank into repair mastery (they’re cheap). After that save up for applied fortitude, then applied strength. Then ram/cata/ac/treb masteries.

Pretty decent thread here. https://forum-en.gw2archive.eu/forum/wuv/wuv/Where-should-I-spend-my-wvw-ability-points/first#post3985313

The general consensus being that you start with supply master 4 and put a rank or two in both build and repair masteries to make the mot out of your early points. In terms of guard stacks defense against guards is almost always recommended first.
